I'm currently researching the possibilities on realculating data with PI Analytics. I was asking techsupport if PI Analytics supports recalculation, but I was told it supports only backfilling.
The difference is that backfilling requires the output tag to have no values in the time the tag values should be recalculated.
This means to me that recalculation would require me to delete all values before backfilling for a specific time range.
I was looking at the AF SDK documentation but could not really find a hint on how backfilling could be initiated... Any hints on this?
